Movement-related potentials were recorded preceding self-paced voluntary movements in patients with Parkinson's disease and in healthy subjects of the same age group. We compared the Readiness Potential preceding joystick movements in a fixed direction and preceding joystick movements in freely selected directions. In normal subjects the Readiness Potential amplitude was higher preceding freely selected movements than preceding movements in a fixed direction. The Readiness Potential in Parkinson patients failed to be modified by the different modes of movement selection. The modulation of the Readiness Potential by different ways of preparing for movement might be due to the supplementary motor area (SMA) being more strongly engaged by tasks requiring internal control of movements than by tasks that are externally structured. The results suggest that this task-dependent variation of SMA activity is reduced in Parkinson's disease. A failing capacity to adapt SMA activity to different task demands has previously been suggested by evidence from positron emission tomography studies using similar tasks. 相似文献

OBJECTIVES. To investigate whether care of elderly and disabled patients could be more cost-effective after a short-term hospital stay, we examined the impact of a primary home care intervention program on functional status, use and costs of care after 6 months. METHODS. When clinically ready for discharge from the hospital, chronically ill patients with dependence in one to five functions in personal activities of daily living were randomized to physician-led primary home care with a 24-hour service, and the controls were offered ordinary care. Physical, cognitive, social, and medical functions were assessed in 110 team subjects and 73 controls. Data regarding inpatient days and outpatient visits were collected and converted to costs. RESULTS. Team patients demonstrated better instrumental activities of daily living and outdoor walking and significantly fewer diagnoses and drugs at 6 months. They used less inpatient and more outpatient care compared with the control patients. Significant cost reductions were found in the team group. CONCLUSIONS. This primary home care intervention program is cost-effective, at least for a selection of patients at risk for long-term hospital care. 相似文献

Between 1986–1990, 290 patients with squamouscell carcinoma of the hypopharynx were assessed at the S. S. K. M. Hospital Calcutta,
out of the total of 1460 number of Head Neck cancer, (19.8%). The most frequent initial symptom was a foreign body sensation
in the throat (70%), and males were affected more than females (9.8 : 1.2). The peak age incidence was found between 40 and
50 years (24%). Most of the patients came in advanced stages with cervical lymph node metastases (60%).
One interesting fact that came out from the present study is the Right pyriform fassa was more commonly affected than the
left in righthanded persons (56.9%). Though the reason is not clear it could be due to right — sided swallow, as one side
may be predominant in funtion. 相似文献

Infective conjunctivitis and corneal scarring in three brothers with sex linked hypogammaglobulinaemia (Bruton''s disease). 下载免费PDF全文
T T Hansel D P O''Neill M L Yee J M Gibson R A Thompson 《The British journal of ophthalmology》1990,74(2):118-120
The ocular findings in three brothers with Bruton's disease are reported. All three boys had purulent conjunctivitis, but the two older brothers also developed marked corneal scarring with visual impairment. Haemophilus influenzae was cultured from conjunctival swabs; it was resistant to neomycin but sensitive to chloramphenicol. Tear analysis showed that the three subjects had normal levels of lysozyme but no detectable IgA. 相似文献

There are only a few reports of well defined cystic lesions of the peripheral skeleton following fracture. In children, these lesions are mostly small cortical defects affecting the distal radial metaphysis after a greenstick or torus fracture. A cyst is reported complicating a greenstick fracture, together with a brief review of published reports confirming that these are asymptomatic lesions which can be managed conservatively without further investigation. 相似文献

The association of non-insulin-dependent diabetes mellitus with perceived quality of life in a biethnic population: the San Luis Valley Diabetes Study. 下载免费PDF全文
E M Caldwell J Baxter C M Mitchell S M Shetterly R F Hamman 《American journal of public health》1998,88(8):1225-1229
OBJECTIVES: This study evaluated the association between quality of life and non-insulin-dependent diabetes mellitus (NIDDM) status, and whether this association differs between Hispanics and non-Hispanic Whites. METHODS: Between 1986 and 1989, cross-sectional data on perceived quality of life (PQOL) were collected from 223 persons with NIDDM and 753 non-diabetic subjects. RESULTS: After adjustment, persons with NIDDM rated their PQOL significantly lower than did control subjects. The relationship of diabetes and PQOL did not differ by ethnicity. The number of complications of diabetes was not associated with lower PQOL scores. CONCLUSIONS: Control and treatment strategies should reflect an understanding of the impact that diabetes has on social functioning, leisure activities, and physical and mental health. 相似文献
